There are 360 story books and literature books in the library. The number of story books is one quarter more than that of literature books. How many story books are there?
Suppose there are x story books, then there are (360-X) literature books.
x-(360-x)= 1/4(360-x)
2x-360=90- 1/4x
4/9x=450
x=200
360-200= 160 (Ben)
Answer: There are 200 story books and 160 literature books.
